Called from where? :) I think Tanel, Mladen and you missed the ironical point -- if it can't be called from SQL why it is a deterministic one?

It was very simple question asked for fun -- Mladen who said: "Hey, I'll sue you for using my code. My code is fair and balanced and you cannot use it without paying royalties." :) So, he put "deterministic" clause then. :)

P.S.: Tanel, I do not need an example, it was a joke.
